What is Gemini?
Gemini is Google's family of multimodal large language models — the engine behind the standalone Gemini chat product, the answers inside Google AI Overviews, and the AI features embedded in Workspace (Docs, Gmail, Sheets). For B2B tech GEO, Gemini matters on two fronts: it decides which sources Google AI Overviews cite in the classic SERP (the largest AI answer surface by volume), and it increasingly shapes enterprise buying research done inside Workspace, where analysts and buyers ask Gemini to summarize vendors from documents and the web. Gemini's source selection favors freshness, structured data, and publications with strong entity signals inside Google's Knowledge Graph. Crackle PR audits every client for Gemini and AI Overview citation share as a paired KPI — Gemini is the highest-volume AI answer surface in B2B, and its source picks compound directly into pipeline.
“Gemini is the answer engine most CMOs still don't take seriously — which is exactly why the brands that do are quietly running away with the AI Overview real estate.”
